View 3 RepliesI have a 03 4x4 5.4lt supcab with 154k miles. I replaced the shift motor about 40,000 ago but it has always been tempormental like I had to engage it in 4lo in N and then shift to 4hi to keep it in 4hi. Now fast forward to today. Went to shift to 4lo in N and it didn't shift. I only heard the relays click once and then it wouldn't shift into any gear even though the indicator was on PRND123. Didn't matter.
Also, Park didn't engage and the speedometer acted like it was engaged in RN and D. No movement what so ever. I think it might be the shift motor that shifted part way and is stuck in between gears. Is this possible? I drove fine to the dirt road and I haven't had problems other then the shift motor being touchy. I don't want to pay for a new tranny if it might be the shift motor.
I have a 2003 F150 5.4liter 4x4 and when it is cold I can not get the 4x4 to engage. It is a manual shift for the transfer case not electronic. It shifts but does not activate the 4x4 when it is cold. The 4x4 does work when the temp is about 30 degrees or better. Where to start?
View 1 RepliesI've got a problem with my 4x4 not engaging. I've been ready and re-reading all the related posts and threads and am still confused. Here goes. Early in the fall I had no problem shifting in or out of 4wd. Then when it got well below freezing up here, it stopped working. I had it in a warm shop and all of a sudden it worked fine. After sitting outside again it wouldn't work.
When it was warm, I had no problem shifting in and out of 4x4, dash lights functioning as normal. As it got colder it only seemed to work if I really pulled quite hard on the stick and the 4Low indicator didn't work but 4Low was obviously engaged. Now after another day or two outside, nothing happens at all. When the diff does engage, shifting out of 4x4 is never a problem.
Transfer case seems fine as the front drive shaft turns when I shift into 4H and drive forward. After researching a bit, I crawled under and pulled the blue line off the actuator and had someone shift into 4H, I couldn't feel any vacuum so figured it must be the engage solenoid especially since, shifting out of 4x4 is never a problem.
My question now is, shouldn't the lights on the dash be on even if the solenoid isn't working? I am now starting to wonder if its the sensor switch on the transfer case but I don't see how freezing should affect the switch and would think I'd have issues shifting out of 4x4 as well as in. If I put it in 4X4 and test for current at the solenoid and it is there, can I assume that the switch is fine and the problem is in fact the solenoid?
Ok, have a 2003 fx4 auto trans with manual 4x4 ...I notice more and more that say at intersections, when I start out either turning left or right it feels like the 4x4 is slightly trying to engage, or a chuttering feeling..best that I can describe it. any thoughts, I have 106 K and do need to change out the diffential oils etc.

So the deal is I had to use a slim jim to open up my truck door the other day. Door still locks/unlocks fine, only not with the key. Key will still fit & turn the barrel without any prob. just doesn't engage the lock. Took the door panel off and it looks as if the Rod that connects the inside of the key barrel to the lower (part)? not familiar w/name. has come loose.
Looking for a diagram/picture of how it should look to get everything put back together so the key'll work again. Sucks unlocking passenger side and climbing over to open driver door.
Just tried to engage my 4x4 today to see if it was working and nothing. It is the electronic shift on the fly. I started checking the vacuum hoses and found one that looked like a mouse chewed threw part of it and repaired that line. Still no 4x4. So...there are no lights coming on, no sound from the transfer case shift motor and no noise of any kind when cycling the shift ....
I pulled the connection apart at the shift motor to test for voltage with 2hi and truck running and no 12volt. I tested all the pins but not sure if i did it correctly. Also the shift motor itself is rusty on the outside casing. What pin to test for voltage?
I have 1999, F150 5.4L with electric 4wd shift. I put it in 4high just fine and smooth. Now 4lo on other hand rough shift if it goes in 4lo, sometimes won't engage but 4 high works fine. What's the cause
View 2 RepliesI recently bought a 1997 f150 4x4 with shift on the fly. I bought the truck from an old man who parked it outside his house. I love the truck, but the 4x4 has been finiky. I have done a ton of research and i have done a bunch of testing. The vacuum system is working correctly. I have tested the solenoids and the front axle actuator is working properly.
There is some kind of electrical issue. It might be the GEM (i really hope not), but it might be the shift on fly switch itself.
The 4x4 will engage, but when i turn the switch to 2h nothing seems to happen. Driving in reverse doesn't work. But sometimes it switch from 4h to 2h, just by turning the truck off and restarting it. If restarting doesn't work, then i have to pull the 5 fuse, let it sit, then put it back in. I read that this resets the GEM. (Number 5 fuse, middle row, 5th from the top).
Resetting the GEM usually does it, but not all the time. Sometimes it will still be in 4x4 again after resetting the gem. And then what is really weird, after driving it in 2h (after the gem reset) then turned it off and restarting it, it will go back into 4x4. All this happens with the switch set to 2h. So I have been having to reset the GEM, each time i restart it. (This was going on for a day or so.)
Any easy testing i can do? Do you think it could be the switch on the dash, or more likely to be the gem? I hope it isn't the gem. I don't want to have to pull a fuse each time to drive my truck.
I just bought a 2000 f150 4x4 ex cab with the 5.4. Once in a while when starting, there is a grinding and the starter won't engage the flywheel. The truck has only had 17000 miles put on it in the past 4 years, and has sat quite a bit. Could the starter gear be gummed up and not engaging all the way, or should the starter be replaced? Or could poor contact on the cables cause this? Or is this a flywheel issue?

All fuses inside and under hood checked good and still cruse control will not engage. All other functions work: brake lights, turn signals, etc. Green cruise light is operational, checked pin #10 on wiring harness at servo,amplifier unit under hood and have good ground. The Cruise ON button will not turn on cruise control system and will not light green cruse light.
View 4 RepliesI have a "rapid blink" when I engage the right turn signal. It doesn't do it all the time. When I checked it, the rear was blinking and the front appeared to be out. Changed the right front bulb, but the problem didn't go away. So, I changed the rear bulb. Still didn't cure it. Now I'm confused. I thought for sure "rapid blink" was caused by a bad bulb. What else could it be, Flasher unit? Bad ground?
View 14 RepliesThe problem started with a front seal leak a few months ago which I had no choice but to continue driving with because of low funds. I don't drive much so a couple of quarts of ATF was usually enough to get me out and about for what little driving I had to do. I know.. a front seal is cheap, but I'm partially disabled and unable to work on anything that is not under the hood.
I finally scraped up enough money to hire a friend to replace the seal, but he had a life crisis before completing the work, so I had to get another friend to reinstall the trany... still had the leak, but I could get around by adding ATF as before.
So we tried again... dropped everything and put another new seal on. This stopped the leak, but we got some grinding/squealing noises and could not get the trany to engage any gear.
From reading forum posts and other sources, we decided to replace the TC which we just completed this evening. We got some more of the grinding / squealing noise like before, except that it only occurred the first time we tried cranking the engine, the 2nd time we got no noises, but again no gears engaging.
What to check/replace next assuming there is something we can look at other than a total trany rebuild or replacement. I personally find it hard to believe we could have gone from a tolerably functional trany to scrap metal just replacing a seal and the TC. Its gotta be something simple we overlooked !!
My 2002 f150 blows the overdrive fuse (#29) every time the overdrive tries to engage. Could it be the overdrive switch? Where is that switch? Could it be a speed sensor? Truck has an automatic transmission and a 5.4 engine.
View 14 RepliesAfter getting the oil changed in my 1997 Ford F-150 4.6L with 150K miles at a local quick lube, I made one stop and my truck wouldn't start. I could hear the starter engage the flywheel, but couldn't turn it over at all. Oil was clean and full. I bench tested the starter and it tests good. I put a breaker bar on the crankcase nut and I could barely move it. Oil level was about 2 quarts low before oil change.
View 10 RepliesI engage my 4wd all the time to keep it working and lubed up. tonight i turned it on and it was making a light clicking noise like a card in the spokes of a bike (not loud) and there was no vibrations or nothing that really sounded bad..what could be making this noise, what should I look for...
View 5 RepliesI have a 1998 F-150 and when shifting into 4 wheel drive (manual floor mount shifter) the drive shaft from the transfer case turns but the wheels do not engage.
Looking for a diagram of how the axle works?
4x4 wont work, when I shift the lever on the floor it doesn't engage so i bought two new solenoids.. didn't work, have power on both solenoid connections. If I unhook my vacuum lines from the solenoid, I can push the Actuator rod in making my 4x4 work. I've gone threw everything.. have vacuum, have power on my solenoids. Just nothing works when I shift into 4x4 on the floor.
View 3 RepliesI have a 2000 F-150 XLT Supercab 5.4 4x4 with the dash shifter. My front axle won't engage when shifting into 4x4. A few months ago the vacuum solenoids were replaced and they sound as though they are functioning properly. The diaphragm isn't moving the lever thing and i can't get the lever to move with a screwdriver either.
I know it has worked the past two weekends. Two weeks ago it was in a significant amount of mud and possibly submerged at times. I power washed everything pretty good immediately afterwords though and it has worked in between then and now. What could be going on?
I have a 99 F150 5.4 V8 4x4, My problem is when I engage 4Hi the dash light "low range" turns on but NOT the 4x4 light. Now if I go to 4Low the 4x4 light turns on(Low Range light stays on). So in essence the lights are backwards. In 4Hi it is not engaging 4 wheel drive. Also its a SOTF not electronic selector.
View 2 RepliesI have a 2001 supercab 4x4 with a 4.6 in it, it has 186k on it and the only issues I've had was a misfire not to long ago. I replaced the plugs and coil packs and fixed that issue. 2 days ago she ran fine with no issues and this morning I went out to go to the store and she wouldn't start. All the dash lights come on and all of that normal stuff when you turn the key. When I turn the key I hear what sounds kind of like a clunking noise towards the bottom of the windshield and the middle of the dash. The starter does not engage, no nothing, really confused here. I thought maybe the battery was bad so I put my jumper on it and tried but again nothing happened.
